Now that you are familiar with applets, you may be wondering how to write them. The
organization that developed the Java programming language, Sun Microsystems, offers
documentation and other resources on their Web site at
http://java.sun.com.
Be aware that
the Java programming language is very powerful, but quite complex. There are many
resources for free and commercial Java applets on the Web. Here are a few helpful sites:

As you visit these and other Java resource sites, keep in mind that some Java applets are
copyrighted. Be sure to obtain permission from the creator of the applet before using it on
your site. There may be some requirements for giving credit to the creator either by name
or by linking to their Web site. Follow the instructions provided with the applet. Some
applets are free to use in personal Web sites but require licenses for commercial use.
FAQ
Why do we still use the
<applet>
tag if it is deprecated?
Although the applet tag is deprecated, it is better-supported in commonly used browsers than

tag to display a Java applet is shown

<object codetype="application/java" classid="fader26.class"
width="610" height="30">
<param name="AppletHome" value="http://www.crosswinds.net/fader/" />
<param name="Data" value="mymessage.txt" />
<param name="bgColor" value="#000000" />
</object>

JavaScript is an object-based scripting language. In JavaScript you work with the objects
associated with a Web page document: the window, the document, and the elements such
as forms, images, and links. JavaScript, developed by Netscape, was originally called
LiveScript. When Netscape collaborated with Sun Microsystems on modifications to the
language, it was renamed JavaScript. JavaScript is not the same as the Java programming
language. Unlike Java, JavaScript cannot be used to write stand-alone programs that can
